Application examples

Application examples application example

western blot using anti-GI antibodies

50 µg of total protein from Arabidopsis thaliana extracted with TRIZOL protocol and finally dissolved in buffer E (Martínez-García et al., 1999, Plant J 20:251-7), was denatured with SDS at 95 C for 5 min, were separated on 12% (w/v) acrylamide/bis-acrylamide SDS-PAGE and blotted 10 mins to nitrocellulose using semi-dry tank transfer. Blots were blocked with 5% (w/v) skimmed milk in TBSt (Tris-Buffer Saline + 0.1% (v/v) tween-20) for 2h at room temperature (RT) with agitation. TBSt Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 2h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly, then washed 4 times for 15 min in TBSt at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in TBSt for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL (Life Science). Exposure time was continuous for 10 mins in a CCD camera. The image was taken after 5 min exposure.
